Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The organelles that break down lipids, sugars, and proteins into small molecules that can be used by the cell are called
A
vacuoles
B
lysosomes
C
ribosomes
D
microfilaments
Explanation: 

Detailed explanation-1: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.

Detailed explanation-2: -A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.

Detailed explanation-3: -Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.

Detailed explanation-4: -Lysosomes are acidic organelles containing at least 50 different hydrolases that degrade a wide variety of macromolecules, including DNA, proteins, carbohydrates, and lipids delivered via autophagy and other endocytic pathways.

Detailed explanation-5: -They are not found in plants, but vacuoles perform the role of lysosomes in plant cells. Lysosomes are known as Suicidal Bags as they tend to destroy the cell membrane with its digestive enzymes, causing lysis of the cell (also called autolysis)
